DOOR AND LOCK THEREFOR.

T 0 all whom it may concern:

Be it known that we, ELMER B. STONE and GHARLES'E. JOHNSON,'e2LOl1 a citizen of the United States, and a resident of New Britain, in the county of Hartford and State of Connecticut, have invented a new and Improved Door and Lock Therefor, of which the following is a specification.

Our invention relates more especially to the class of locks employed for securing doors and similar devices, and an object of our invention, among others, is to provide a removable lock that may be applied to different doors, but that shall be adapted for use particularly in connection with doors or similar devices especially constructed to receive it: and a further object of our invention is to provide a lock having simple means for indicating certain conditions: and a further object of our invention is to so construct a lock that the door and door cas ing shall be rigidly united, whereby the bolt may not be surreptitiously disengaged from its keeper.

One form of door, frame and lock therefor, embodying our invention is shown in the accompanying drawings, in which- Figure 1 is a face view of a door frame and door showing the latter locked with our improved lock, the signal being in the position assumed when the lock has been secured by the use of a master key.

Fig. 2 is a similar view showing the position of the signal assumed when the lock has been secured by a common key.

Fig. 3 is a face view of a part of a large door and frame with parts broken away to show construction, and with the signal in the same position as shown in Fig. 2.

Fig. 4 is a view showing the lock plate and lock supported bythe door frame in position to permit opening movement of the door.

Fig. 5 is a view of the lock plate and lock, the latter being cut in section on plane denoted by dotted line 5-5 of Fig. 8, the bolt being removed. I v

Fig. 6 is a view in cross section through a portion of the door and .frame with my improved lock secured thereto, the latter being broken away on plane denoted by dotted line 66 of Fig. 5.

Fig. 7 is a view of the lock case with the back plate removed.

Fig. 8 is a view in, section through the lock case and plate on plane denoted by dotted line 88 of Fig. 4, and the parts, however, being reversed end for end, the tumblers being omitted."

Fig. 9 is a view similar to Fig. 8 but on plane denoted by dotted line 99 of Fig. 5, and the parts outside of the lock case being omitte V Figs. 10 and 11 are views of the keys, the former the master key and the latter the ordinary key used in our improved lock.

Our improved locking means, while not confined to any particular use, is especially applicable in securing the doors and lockers such as are provided in gymnasiums and similar places. The articles used by the members and permanently stored in such places commonly occupy much less space than is required by the members for the temporary storage of wearing apparel and other artlcles during the use by such members of the gymnasium or similar places, which use is generally for' comparatively short periods. comparatively few members occupy a gymnasium or similar place at any one time and it is thereforecustomary to provide only such numbers of large lockers as 'may be required for use of a maximum number of such members at any one time, and small lockers to contain the personal equipment of each member for permanent storage the number of the large being much less than those of the small lockers, and space being thus economized.

Our improved lock forming the subject matterof this application is constructed for use in securing the doors both of the small and large lockers hereinabove referred to,

the lock being also so made that it will be of little use in other places, and therefore there will be no object to the appropriation of the lock for other uses, and the liability to theft is thereby removed. In the drawings the numeral 10 indicates a door frame and 11 the door of a small locker hereinbefore referred to and commonly used in gymnasiums and similar'places, and the numerals 12 and 13 indicate respectively the door frame anddoor of one of the larger lockers above referred to. These are usually of sheet metal and in order to prevent disengagement of the lock bolt from its keeper by springing the door and frame apart we so construct our improved lock that it rigidly secures such door and frame together and prevents their separation while the lock parts are engaged. In accomplishing this result we provide a lock'plate 1 1, preferably dish-shaped, having a bent flange 15 extending from one edge thereof and adapted to pass through a slot 16 through the door frame 10, it being understood and intended that the description herewith applies generally to the doors and frames of both the small and large lockers. This bent flange has a nose 17 adapted to underlie the door frame, and by reason of this structure the door of the locker may be opened without removing the lock from the frame, the latter being swung on the bent flange as a pivot to a position to permit the door to be opened and as shown in Fig. 4 of the drawings, the nose 17 preventing disengagement of the lock late from the door frame.- It

will be 1m erstood that the nose, flange,

. turned flanges 19 to receive screws or other devices for securing the lock case to the lock plate. Openings 20 are formed through the doors 11 and 13, the same numbers being employed in connection with the doors and frames of the large and small lockers as they arethe same except for size. These openings are of the shape and size, approximately that, of the lock case 18, so that the latter may be readily passed through the openings, as shown in Fig. 6 of the drawings, in which position the lock will be held by means of its bolt 21 which, when thrown,

asses behind the door, as shown in the gure of the drawings last referred to. It will be seen that when the lock plate is thus secured to the door with the flange 15 engaging behind the door frame and the plate extending across the gap or. crack between the edges of the frame and door, the latter will be so rigidly secured together that it will be impossible to spring them apart sufficiently to permit removal of thelock plate.

The case 18 contains a slotted barrel 22 adapted to receive keys, and at one side of v the barrel a number of tumblers 23 are pivotally mounted and have slots to. receive a lug 24 projecting from the side of the bolt 21, the latter having a tail 25 with a notch to be engaged by a projection from the edgeof the key and'by means of which the bolt is moved. The barrel, bolt and tumblers just described may be of any well known construction and a further and detailed description is, therefore, omitted herein.

WVe provide our improved lock with means for indicating to an attendant the fact that a locker has been occupied and therefore needs attention for the cleansing of gar- 'ments that may have been replaced in the locker or for other purpose. This mechanism consists of a signal plate 26 pivotally attached to the inner surface of the lock plate 14 and adapted to swing across the signal opening 27 through said plate. This signal plate may be designed to denote use of a locker when in either of its positions, in the arrangement herein shown the uncovering of the opening 27, as shown in Figs. 2 and 4, indicating such use of the locker and, therefore, the requirement for attention. In such an arrangement it is preferred that the color of the signal plate be substantially that of the face of the lock plate, and the door immediately back of or in line with the opening 27 may be of any contrasting color to clearly bring out the fact that the opening is uncovered. A spring 28 is so attached to the plate 26 as to force the latter normally to non-indicating position, thatis, a position covering the open ing 27. A signal actuating bar 29 is pivotally attached to one end of the signal plate, the opposite end of said 7 bar extending through an opening in the lock case 18 within which said bar has a locking notch 30, a bar actuating shoulder 31 and aslot 32 within which the end of a post 33 project ing from a wall of the case is received. The bar actuating shoulder 31 is engaged by a signal actuator 34; slidably mounted against one of the side walls of the lockcase, and adapted to be forced in one direction by means of an actuator spring 35. The spring 35 is stronger than the signal plate spring 28 and has, therefore, suflicient force to move the signal plate 26 and uncover the opening 27. A stud 36 projects from the side of the actuator 34 through a slot 37 diagonally arranged in a wall of the case 18, said stud projecting far enough to engage the outer face of the locker door when the lock plate is forced to place, and as shown in Fig. 6 of the drawings. In this operation of forcing the lock plate to place against the outer surface of the door, the stud 36 moving along the slot 37 draws the signal actuator 34 away from the shoulder 31 on the signal actuator bar, and as shown in Fig. 5 of the drawings. The bar 29 is at-this time free to be moved by the signal plate 26 under force of its spring 28 and into position to close the opening 27, in which position it indicates that no attention to the locker is required.

A signal controller 38 is pivotally mounted on the post 33 and it has a locking lug 39 arranged to engage the locking notch 30 in the signal actuating bar 29. A controller lug 40 also projects from the controller into position to be engaged by a controller actuating prong 41 extending from the master tumbler 42, which tumbler is mounted upon the pin supporting the other tumblers of the lock hereinbefore referred to. This master tumbler, except for the prong above mentioned, is of the usual construction and operates in a manner common to many locks in use at the present time.

It being remarked that the lock parts of themselves and independently of our improvement are of ordinary construction in which the master tumbler is operated only by the master key 44 and it being assumed that the parts of the device are in the position in which they have been left when secured to a door by use of said master key, as by an attendant, and as shown in Fig. 1 of the drawings, the operation of the device is as follows:

The operation of theregular occupants key 43 will not affect the signal apparatus in any manner whatsoever. Therefore, when the occupant throws the bolt 21 by the use of his key to release said bolt from engagement with the door 11 of the small locker (or that of the larger locker) the signal mechanism 7 will not be affected. The lock plate will, however, as soon as the bolt is drawn inward into the case and thus released from engagement with the back surface of the door, spring outwardly at that edge opposite the flange 15, owing to the pressure of the stud 36 against the outer surface of the door and caused by the actuator spring As the signal actuator 34 is thus drawn back by the spring 35 pressure of the actuator against the shoulder 31 will be exerted upon the signal actuating bar 29 and the signal plate 26 will be moved to its indicating position as shown in Figs. 2 and 4 of the drawings. When the locking notch '30 in said bar reaches a position opposite the locking lug 39, the latter will drop into said notch under the action of gravity and the controller actuating spring 45 (either or both) and the signal plate will thus be held in its indicating position until the controller is again moved, as by the operation of the master tumbler 42] The occupant may remove from the small locker such articles as he Wishes to use and selecting one of the larger lockers he places his wearing apparel therein, removing the lock plate 14 from the door of the smaller locker to the door'13 of the larger locker and the latter may be secured by the use of his key. \Vhen the occupant wishes to again resume his wearing apparel the larger door 13 is unlocked as before described with respect to the small door, the equipment is replaced in the small locker and the lock is removed to the door of the small locker where it is again secured, and during all of this operation the signal device remains in the position assumed by it when from behind the door of the small locker and with the master key 44, the operation of the master tumbler 42 by said key will swing the signal controller 38 in position to remove the lug 39 from the locking notch 30 in the bar 29 and the spring 28 will promptly move the signal plate 26 into position to cover the opening 27 and as shown in Fig. 5 of the drawings. lVhen, however, the bolt has been withdrawn, the lock plate 14 will be pressed outwardly by the stud 36 as hereinbefore described, and the operation of the actuator 34, and the bar 29 will move the signal plate 26 to uncover the opening in which position it will be held by the automatic engagement of the locking lug 39 with the notch 30. The lock plate may now be moved to the position shown in Fig. 4, the nose 17 retaining it from disengagement from the frame 10. The door of the locker having been opened and the locker given the required attention and the door being again closed and the lock plate swung to its closed position the master key will be employed to lock the parts. In this operation the master tumbler 42 will again operate to release the lug 39 from the notch 30, and the actuator 34 being in a position away from the shoulder 31 the spring 28 will move the signal plate 26 into position to close the opening 27 and as shown in Fig. 1 of the drawings, after which the operation above described may be repeated.

To facilitate the movement of the signal controller 38 a bearing lug 46 projects from one face of the controller and rests against an inner face of. the key case.
